What's so special about this beer? Keep the North Cold is a golden ale that uses all Minnesota-grown ingredients. Most notably of these, it contains Kernza, a perennial grain with root systems up to 10 feet deep. Kernza doesn't need to be tilled every year, so it fosters healthy soil that absorbs carbon dioxide from the atmosphere and locks it securely in the round. A portion of proceeds from sales of the beer will be donated to organizations on the leading edge of solutions to the climate crisis.
